The pin that sticks is in the bottom, you don't need to disassemble to get to it, it sits on top of the air metering flap arm.

You may have toasted the fuel distributor, I don't recommend taking them apart as they never seem to work properly afterwards.

No start with added fuel is likely the broken rotor carrier, it's fairly common.
